What is the force of Q2 on Q1? And it simply states that the magnitude of the force between two point charges is directly proportional to the product of the magnitude of the charges and it is inversely proportional to the square of the distance separating them. So F21 is the force on Q2 due […]

Can we separate the poles of the magnet? magnet poles can never be separated. Do magnets attract north to south? All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of […]

How many 0.2 centimeter are there in 6.11 meter? 30.55 Which is big CM or M? A centimeter is 100 times smaller than one meter (so 1 meter = 100 centimeters). A dekaliter is 10 times larger than one liter (so 1 dekaliter = 10 liters). Here is a similar table that just shows the […]

What is the difference between the layers of the earth? The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases. What is […]

What is the overall reaction rate law? A The rate law for step 1 is rate = k1[NO2]2; for step 2, it is rate = k2[N2O4][CO]. B If step 1 is slow (and therefore the rate-determining step), then the overall rate law for the reaction will be the same: rate = k1[NO2]2….Answer. step 1 NO+NOk1→N2O2 […]

Can you trickle charge a battery while it is connected? If your question was if it is OK to trickle-charge a battery while it is connected to the car’s electrical system the answer is yes. I have a 2 amp trickle charger on my 97. It is hooked to a timer and runs for 30 […]

What if electronic safe lock fails? If it fails there are locksmith who can hook up their keypad to it and open the door. The only instance that this would work would be if you had a keypad failure. Any issue with the lock has nothing to do with the wiring coming out of the […]

What is the activation energy of a reaction quizlet? Activation energy is the energy required to break existing bonds, and form new bonds. If a collision occurs with more energy than the activation energy, the reaction will occur. Is activation energy always positive? Although the energy changes that result from a reaction can be positive, […]

Does internal energy depend on heat? The internal energy and enthalpy of ideal gases depends only on temperature, not on volume or pressure. From the fundamental equations for internal energy and enthalpy, the volume dependence of internal energy and the pressure dependence of enthalpy for ideal gases are derived. What is internal energy explain giving […]

How does solar energy affect the atmosphere? The radiation warms the Earth’s surface, and the surface radiates some of the energy back out in the form of infrared waves. As they rise through the atmosphere, they are intercepted by greenhouse gases, such as water vapor and carbon dioxide. Greenhouse gases trap the heat that reflects […]
